Supco BC5-100 Capillary Tube 0.028" ID X 100'

The Supco BC5-100 Capillary Tube 0.028" ID X 100" FT is a precision refrigerant metering component that regulates the amount of liquid refrigerant entering the evaporator during the refrigeration cycle. Its narrow internal passage creates a controlled pressure drop allowing refrigerant to expand before reaching the evaporator for proper heat absorption. Refrigerant flow maintains balanced system operation supports stable evaporator performance and contributes to efficient thermal transfer throughout the cooling process in HVAC systems. The element is connected between the condenser outlet and the evaporator inlet as part of the sealed cooling circuit.
